Abstract: The present invention is directed to target assembly for receiving a golf ball comprising a plurality of parallel golf ball receiving elongate channels; each channel having substantially the same width as the other channels and each channel comprising a plurality of discrete golf ball receiving zones. That the channels may be adjusted and adapted to provide one or more consolidated target for players to aim for on the golf ball putting practice device. The sub-divisions of each channel and the plurality of channels form a grid structure.  By assigning different scores to the different subdivisions of each channel, one or indeed multiple targets can be formed. These targets can be then altered to prevent 'muscle memory' effects from assisting a player to achieve a high score.

Abstract: Selon l'invention, en rapport avec un signal représenté dans un domaine fréquentiel, une analyse de prédiction linéaire est réalisée dans le sens de la fréquence selon un procédé de covariance ou un procédé d'auto corrélation, de sorte à obtenir un coefficient de prédiction linéaire. Selon l'invention également, la résistance d'un filtre est ajustée par rapport au coefficient de prédiction linéaire obtenu, et l'enveloppe temporelle du signal est ensuite transformée en filtrant le signal dans le sens de la fréquence avec le coefficient après ajustement. Dans ces conditions, dans un procédé d'extension de bande dans le domaine fréquentiel représenté par SBR, un pré-écho ou un post-écho qui sont susceptibles de se produire, sont réduits sans augmentation significative du débit binaire, ce qui permet ainsi d'améliorer la qualité subjective d'un signal de décodage.

Title: Sensitive differential pressure sensor and method
Inventor: WOOTTEN KEITH ROBERT
IPC: G01L13/02
Filed: 2011-12-15
Abstract: A differential pressure sensor has a magnetized piston free to move in a cylinder.  Magnetic endcaps seal the ends of the cylinder, forming chambers on either side of the piston. The moveable magnetic piston is constrained by the opposing magnetic fields of the endcaps. The piston is covered with magnetic ferrofluid, providing a low friction gas-tight seal around the piston. The cylinder has two pressure input lines, one being connected to the chamber on either side of the piston. The relative pressures of the input lines cause the piston to move to a position of equilibrium within the cylinder, with the magnetic fields of the endcaps holding the piston in place against the pressure. A  magnetic field angle sensor detects flux lines on the outside of the cylinder, and the reading is correlated with the pressure differential between the two input lines.
